Abstract

The invention relates to a winding misaligned hub motor device, comprising a stator core and a rotor core disposed on the periphery of the stator core, wherein the stator core comprises a plurality ofmodular stator cores, each modular stator core comprises a middle tooth and two side teeth respectively located on two sides of the middle tooth, the plurality of modular stator cores are connected to each other along the circumference to form a plurality of teeth arranged along the circumference, the stator core is provided with three-phase dislocation windings, the winding mode of the three-phase dislocation windings is that the adjacent three modular stator cores are grouped, the windings on one or the two side teeth of the same position in each modular stator core in each group are woundby a plurality of layers, the side teeth having a plurality of layers of wound windings are wound with current phase winding and the phase windings on adjacent modular stator cores, and the other teeth are provided with single phase windings. The invention is capable of improving the electromagnetic characteristics of the motor output by weakening the even harmonics induced by the continuous polemagnetic imbalance in the back electromotive force and reducing the torque ripple.

Description

technical field [0001] The invention relates to the technical field of electric motor manufacturing, and in particular to a winding dislocation wheel hub motor stator and a winding dislocation hub motor device, which are suitable for new energy vehicles and other application occasions that require direct drive of an outer rotor. Background technique [0002] With the promotion of green and low-carbon travel, energy conservation and emission reduction policies, distributed drive technology for new energy electric vehicles has gradually developed. Compared with the centralized motor drive of the current mainstream electric vehicles, the distributed drive system simplifies the vehicle structure. The distributed drive evenly distributes the motor power to the four independent wheels, and the hub motor integrates the power, transmission and braking devices into the hub. Inside, the vehicle drive system no longer needs traditional mechanical gear shifting, clutches, transmissions,...
